Professor Alan Reilly:

We did not have a tip-off for this study. We initially went out and took burgers from nine different manufacturers. When the burgers came back, we focused on those companies where we found burgers to be positive for equine DNA.

I included the information in my presentation relating to the focus on cheaper ingredients and global sourcing to give the general background as to what informs the types of study we carry out. There was certainly no tip-off.
